It provides a unified namespace and reduces latency by keeping frequently accessed data closer to compute resources, improving performance for workloads like media processing, machine learning, and big data analytics. ``` aws.fsx_file_cache ``` ## Fields | Title | ID | Type | Data Type | Description | | ------------------------------- | ---- | ------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------- | | _key | core | string | | account_id | core | string | | creation_time | core | timestamp | The time that the resource was created, in seconds (since 1970-01-01T00:00:00Z), also known as Unix time. | | data_repository_association_ids | core | array | A list of IDs of data repository associations that are associated with this cache. | | dns_name | core | string | The Domain Name System (DNS) name for the cache. | | failure_details | core | json | A structure providing details of any failures that occurred. | | file_cache_id | core | string | The system-generated, unique ID of the cache. | | file_cache_type | core | string | The type of cache, which must be LUSTRE. | | file_cache_type_version | core | string | The Lustre version of the cache, which must be 2.12. | | kms_key_id | core | string | Specifies the ID of the Key Management Service (KMS) key to use for encrypting data on an Amazon File Cache. If a KmsKeyId isn't specified, the Amazon FSx-managed KMS key for your account is used. For more information, see Encrypt in the Key Management Service API Reference. | | lifecycle | core | string | The lifecycle status of the cache. The following are the possible values and what they mean: AVAILABLE - The cache is in a healthy state, and is reachable and available for use. CREATING - The new cache is being created. DELETING - An existing cache is being deleted. UPDATING - The cache is undergoing a customer-initiated update. FAILED - An existing cache has experienced an unrecoverable failure.

This ID is a 12-digit number that you use to construct Amazon Resource Names (ARNs) for resources. | | resource_arn | core | string | The Amazon Resource Name (ARN) for a given resource. ARNs uniquely identify Amazon Web Services resources. We require an ARN when you need to specify a resource unambiguously across all of Amazon Web Services. For more information, see Amazon Resource Names (ARNs) in the Amazon Web Services General Reference. | | storage_capacity | core | int64 | The storage capacity of the cache in gibibytes (GiB). | | subnet_ids | core | array | A list of subnet IDs that the cache will be accessible from. You can specify only one subnet ID in a call to the CreateFileCache operation. | | tags | core | hstore_csv | | vpc_id | core | string | The ID of your virtual private cloud (VPC). For more information, see VPC and subnets in the Amazon VPC User Guide. |
